In the diuwliigs, `l*`ig'ino l, .is :i sido @lleva'tion of :i woltgi'oo'ving :ind liovlling nm whine embodying tlio invention in ,ilprolol) the slide 9 so as tov move up and down with the presser foot. Asshown, the knife blade is curved in the are of a circle, and is formedupon the periphery of a tlat disk which is provided with a notch, oneside of which forms the cutting edge of the knife. The grooving knife issecured to the slide by means of a stud 17 projecting laterally from thecenter of the disk, and held in a.split clamp formed in the lower end ofthe slide 9 by a clamping screw 18. By this construction, the groovingknife may be given a rotary adjustment to bring the cutting edge of thekniferinto the required position as the blade of the knife becomes wornaway in re-grinding it, and may also be given a lateral adjustmenttovary the distance of the groove from the edge of the welt. Also thearrangement of the blade of the groov ing knife in the are of a circlepermits the knife to be so placed in the machine that the portion of theknife directly back of the cutting edge extends in the direction inwhich the welt strip is fed, the cut'surface of the strip beingtangential to the groove of the knife blade, The knife blade thus cutsto the best possible advantage and the chip orstrip removed by the knifepasses easily over the upper surface of the blade.

In order that the depth of the groove which is formed in the welt by thegrooving knife may be regulated as desired, the presser foot is somounted lthat, it maybe adjusted on the slide 9` to vary the extent towhich `the grooving knife projects below the surface of the presserfoot. For this purpose the pressen foot is provided with a verticallyextending portion 19 arranged to en gage one side of the slide 9, andprovided with a' guiding rib 2O which fits within a guiding grooveformed in the face of the slide. The presser foot is held in positionupon the slide by means of a clamping bolt 21 which passes through ayslot formed in the vertical portion 19 of the presser foot, and. isthreaded into a hole in the slide. The means for vertically adjustingthe presser foot upon the slide 9 consists of an adjusting screw 22vided with a flange 23 engaging a recess formed iu the vertical portion19 of the presser foot.

'lhe welt beveling knife is indicated at` 24, and consists of a flatdisk notched or cut away to provide a cutting edge. The disk is securedin position-by means of a stud arranged in the slide, and pro'projecting laterally from the center of the disk, and entering a splitclamp 25 in which it is held by means of a clamp screw 26.

mounted upon a block 28 so as to be capable of an angular adjustment tochange the angle of the bevel produced by the knife on the welt strip.The plate 27 is provided with a curved rib 29 which enters a curved slotformed in the block 28, and the rib and slot are substantiallyconcentric with the point of operation of the knife on the Welt,

so that an angular adjustment of the plate produces no substantialdisplacement of the knife with relation to the Welt. The knife carryingplate 27 is heldin adjusted position by means of a clamping bolt 30passing through a slot in the plate and threaded into the block 2,8. Tovary-the depth of the cut produced by the beveling knife, provision islnade for adjusting the block 28 vertically. As shown, the block 28 isarranged to engage a vertical surface 31 formed on the frame of lthemachine, and is provided With a guiding rib 32 which tits within aguiding slot formed in the surface 31. The block is held in adjustedposition by means of a clamp bolt 33 which passes through a slot 34formed in'.v

the block, and is threaded in a hole in the frame. l i

The welt strip` is fed through the machine by a power operated feedingmechanism which acts to impart a continuous feeding movement to thestrip. This feeding move? ment comprises a driven feed roll 35- andiaspring pressed pressure roll 36 between which the welt strip passes, andby which the strip is pulled through the machine against the action ofthe grooving and beveling knives.

shaft 3S which carries the roll. To enable tlm-machine tobe thrown intoand out of operation, a loose pulley 39 is mounted upon the feed shaft38, and a belt. shifting device 40 is provided for shifting the belt onto either the fast or loose pulley at Willl The belt shifting device issecured upon a shipper rod fll which extends from the front of themachine, where it is provided wit-h a'handle 4-2 by meansof which it maybe conveniently actuated by the operator in throwing the machine intoand out of operation.

lVhen a welt strip is to be inserted in the machine, the spring pressedside guide 5 should be retracted, and to enable this to be convenientlydone, connected mechanism is provided through which the operator maycause the presser foot to be raised, and the The roll 35 is driventhrough a: belt passing over a pulley 37 secured to the sidrfuiile ln hererrn-hal. ln ihe reuslrui' presser feel, and separ: lingT lhe leedrnlls7 'lian shown ilw lower end eif ille prrsfs'er l'nnii si|l`=lanin|lly as desrrilued.
